Mosiah 29: 21-27

21 And behold, now I say unto you, ye cannot dethrone an iniquitous king save it be through much contention, and the shedding of much blood.
22 For behold, he has his friends in iniquity, and he keepeth his guards about him; and he teareth up the laws of those who have reigned in righteousness before him; and he trampleth under his feet the commandments of God;
23 And he enacteth laws, and sendeth them forth among his people, yea, laws after the manner of his own wickedness; and whosoever doth not obey his laws he causeth to be destroyed; and whosoever doth rebel against him he will send his armies against them to war, and if he can he will destroy them; and thus an unrighteous king doth pervert the ways of all righteousness.
24 And now behold I say unto you, it is not expedient that such abominations should come upon you.
25 Therefore, choose you by the voice of this people, judges, that ye may be judged according to the laws which have been given you by our fathers, which are correct, and which were given them by the hand of the Lord.
26 Now it is not common that the voice of the people desireth anything contrary to that which is right; but it is common for the lesser part of the people to desire that which is not right; therefore this shall ye observe and make it your law—to do your business by the voice of the people.
27 And if the time comes that the voice of the people doth choose iniquity, then is the time that the judgments of God will come upon you; yea, then is the time he will visit you with great destruction even as he has hitherto visited this land. (Book of Mormon, Mosiah, Chapter 29)
